Two key changes are coming to college basketball and Michigan coach John Beilein is only half on board.

Following a 2012-13 season that produced the lowest national scoring average (67.5 points per game) since 1981-82, rules will be enforced this season to unencumber offenses and increase scoring.

Beilein called the modifications “very significant changes.”

The first adjustment addresses proper enforcement of the hand-checking rule. Per the NCAA men's basketball rules committee, fouls will now be called for resting a hand or forearm on an opponent, placing two hands on an opponent, using an arm bar to block the path of a dribbler and, lastly, jabbing one’s hand or forearm into an opponent.

Enforcement of the hand-check rule is meant to improve one of the oft-uttered buzz phrases in college basketball -- “freedom of movement.”

Starting this season, a defensive player may no longer slide into the path of an offensive player after he’s jumped (or “started an upward motion”) regardless of whether he shoots or passes. Now, a defender must have his position established before an offensive player leaves his feet in order to draw a charge.

Here, Beilein has uneasiness, whereas most coaches speaking up on the new rules have typically cited the hand-check call (believing it will create more free throws, not more shots/scoring).

Beilein said the new charge/block interpretation “will be difficult for both sides to interpret” -- both sides being the players and the officials. Essentially, it’s easier to see if a defender is in position at the point of impact than it is to see if he already has position established when the offensive player takes flight.

In its official announcement of the rule changes, the NCAA Playing Rules Oversight Panel said the adjustment “will give officials more time to determine block/charge calls.” Committee members also believe the tweak to the block/charge rule will allow for more offensive freedom, provide clarity for officials in making the call and enhance the balance between offense and defense.

“I don't know if I agree right now, but they got some really skilled and well educated men in the game of basketball making those decisions,” Beilein said.

While scoring has gradually dropped throughout college basketball, Michigan steadily averaged between 64 and 67 points over Beilein’s first five seasons in Ann Arbor before soaring up to 75.2 points per game last season.

Beilein said his team’s scoring has risen because “we’ve changed quite a bit to less moving parts than we used to have -- less gears involved so that every gear can be little better in what they do.”

Of course, having two first-round NBA draft picks a year ago (Trey Burke and Tim Hardaway Jr.) also helped.

A national increase or decrease in foul calls should produce an interesting impact on Michigan.

The Wolverines last year finished 346 out of 347 teams with only 12.7 fouls drawn per game, while ranking 16th nationally with just 15.5 fouls committed per game.

Offensively, Beilein is hoping for a boost in trips to the free-throw line. Only 15.3 percent of U-M’s scoring came from the stripe last year, the fifth-lowest total in the country.

“We don’t shoot enough foul shots so hopefully we’ll go to the foul line more until people adjust,” Beilein said, soon adding, “I do think, though, that gradually, people will adjust to the block charge and the hands-on.”

Defensively, Beilein only expects a slight bump in foul calls per game. Not from five fouls per half to 10, but “maybe seven or eight,” he said.
